Beaulieu* INTRODUCTION It is the purpose of th is publi cation to provide a concise , yet comprehensive discussion of the for mations of western Oregon. It is the further aim that the data for each of the formations be as current as possi ble. Consequently, the emphasis has been placed on th e recent literature . Although this paper should not be viewed as a discussion of the historical development of each of the fo rmations, the original reference for each of the units is given . Also, in cases where the historical development of the formation has a direct bearing on present-day problems it is included in the discussion . A wide variety of published literature and unpublished reports , theses, and dissertations was con sul ted and several professional opin ions regarding specific problems were so licited . In recent years re search has been concentrated in the Klamath Mountains and the southern Coast Range and for these regions literature was volumi nous. -
The Boring Volcanic Field of the Portland-Vancouver Area, Oregon and Washington: Tectonically Anomalous Forearc Volcanism in an Urban Setting

Evarts U.S. Geological Survey, 345 Middlefi eld Road, Menlo Park, California 94025, USA Richard M. Conrey GeoAnalytical Laboratory, School of Earth and Environmental Sciences, Washington State University, Pullman, Washington 99164, USA Robert J. Fleck Jonathan T. Hagstrum U.S. Geological Survey, 345 Middlefi eld Road, Menlo Park, California 94025, USA ABSTRACT More than 80 small volcanoes are scattered throughout the Portland-Vancouver metropolitan area of northwestern Oregon and southwestern Washington. These vol- canoes constitute the Boring Volcanic Field, which is centered in the Neogene Port- land Basin and merges to the east with coeval volcanic centers of the High Cascade volcanic arc. Although the character of volcanic activity is typical of many mono- genetic volcanic fi elds, its tectonic setting is not, being located in the forearc of the Cascadia subduction system well trenchward of the volcanic-arc axis. The history and petrology of this anomalous volcanic fi eld have been elucidated by a comprehensive program of geologic mapping, geochemistry, 40Ar/39Ar geochronology, and paleomag- netic studies. Volcanism began at 2.6 Ma with eruption of low-K tholeiite and related lavas in the southern part of the Portland Basin. At 1.6 Ma, following a hiatus of ~0.8 m.y., similar lavas erupted a few kilometers to the north, after which volcanism became widely dispersed, compositionally variable, and more or less continuous, with an average recurrence interval of 15,000 yr. -

It see rus fitting, therefore, to dedi cate to the mem ory of Thomas Cond on, this "Field Guidebook to Geologic Trips al ong Oreg on Highways, " whi ch was prepared for immediate use by the 1959 College Teachers Conference in Geol og y and for future use by the interested public. In the autumn of 1852, the young Reverend Condon and his wife, representing the Home Missi onary Board of the Congregati onal Church, sai led from New York around the Horn to San Francisc o, and fr om there continued their trip to Oreg on. Mr. Condon was forced to leave behind him his ge ology books and his collecti ons of rocks and fossils, which were his hobby . But on ce settled at his first church in St. Helens, Oregon, he soon began to ob serve the geologic formati on s about him, and noted in his first rep ort to the Home Missi on ary Board that the village was "built on a bl uff of porous volcanic rock." Alth ough his early years of pi oneer life in western Oregon left him little time for scien tific research, he tookti me to collect a few rocks and fossi Is.
